Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of machine tool technology, and more specifically, to a CNC machine tool for crankshaft machining with chip collection. Background Technology

[0002] The crankshaft is the core component of an internal combustion engine, responsible for converting the reciprocating linear motion of the piston into rotational motion to output power. Its main body is forged from high-strength alloy steel, precision machined and heat-treated, giving it high wear resistance, fatigue resistance and impact resistance. The crankshaft structure includes key parts such as main journals, connecting rod journals, and balance weights. It is widely used in internal combustion engine equipment such as automobiles, ships, and generators. Its manufacturing requires strict control of dynamic balance and surface finish to reduce vibration and energy loss. Modern crankshafts adopt lightweight design and advanced coating technology to further improve efficiency and lifespan, making them a key component for the efficient operation of power machinery.

[0003] In the existing technology, operators generally need to use CNC machine tools to automatically process crankshafts. However, while existing CNC machine tools have basic processing functions, a large amount of debris generated during processing usually falls onto the processing table after processing. When there is a lot of debris, the operator needs to collect and clean it to avoid negatively impacting the processing. However, this cleaning process requires not only human intervention but also stopping the CNC machine tool, thus reducing the processing efficiency. Therefore, improvements are needed.

[0015] The beneficial effects of the embodiments disclosed herein are as follows:

[0016] 1. This disclosure includes a push plate, a long rod, a connecting plate, a driving rod, and a driven rod. When the first motor starts running, the first circular shaft and the driving rod begin to rotate. The rotation of the driving rod drives the driven rod, causing the driven rod to rotate around the other end of the driving rod. In this process, the other end of the driven rod drives the connecting plate, causing the connecting plate, the long rod, and the push plate to move forward along the inner surface of the sleeve plate. Finally, as the push plate moves, the machining debris remaining above the machining table is pushed into the recycling bin, thus achieving the automatic collection function of machining debris.

[0017] 2. In this disclosure, a first limiting plate, an insert plate, a cylinder, a driving rod, and a second limiting plate are set up. When the second motor starts, the second cylindrical shaft and the driving rod will rotate. At this time, the inner surface of the driving rod will drive the cylinder, thereby causing the cylinder and the insert plate to move to the right. When the right end of the insert plate moves to the right side of the first limiting plate, the insert plate will contact the front surface of the recycling box. At this time, the recycling box will be fixed in the current position by the insert plate, thereby ensuring that the recycling box will not move due to external collisions during the processing.

[0031] like Figures 1-5As shown, this illustration depicts a CNC machine tool for crankshaft machining with debris collection, according to an embodiment of the present disclosure. It includes a base plate 1, a machine tool 2 fixedly connected to the left side of the upper surface of the base plate 1, a machining table 3 fixedly connected to the right side of the machine tool 2, a collection box 25 movably connected to the front surface of the machining table 3, the lower surface of the collection box 25 movably connected to the upper surface of the base plate 1, a push plate 4 movably connected to the rear side of the upper surface of the machining table 3, and a sleeve plate 11 movably connected to the rear surface of the push plate 4. The bottom end of the sleeve plate 11 is connected to the machining table 3. The platform 3 is fixedly connected, and the rear surface of the push plate 4 is fixedly connected to a long rod 5. The rear end of the long rod 5 passes through the sleeve plate 11 and extends to the rear side of the sleeve plate 11 and is fixedly connected to a connecting plate 6. The upper surface of the base plate 1 is fixedly installed with a first motor 7 located behind the processing platform 3. The other end of the output shaft of the first motor 7 is fixedly sleeved with a first round shaft 8. The outer surface of the first round shaft 8 is fixedly sleeved with a driving rod 9. The other end of the driving rod 9 is hinged to a driven rod 10. The other end of the driven rod 10 is hinged to the lower surface of the connecting plate 6.

[0032] When the operator starts motor 7, the first circular shaft 8 and the driving rod 9 will start to rotate. At this time, the rotation of the driving rod 9 will cause the other end of the driving rod 9 to drive the driven rod 10, which will also cause the driven rod 10 to start to rotate. Finally, the other end of the driven rod 10 will drive the connecting plate 6 during the rotation, which will cause the connecting plate 6, the long rod 5 and the push plate 4 to start to move.

[0033] In some examples, mounting posts 12 are fixedly connected to both the left and right sides of the rear surface of the processing table 3. A drive motor 13 is fixedly installed on the upper side of the left surface of the mounting post 12. The other end of the output shaft of the drive motor 13 is fixedly sleeved with a threaded rod 14. The right end of the threaded rod 14 passes through the mounting post 12 and extends to the right side of the mounting post 12. A movable plate 15 is threadedly sleeved on the outer surface of the threaded rod 14. The lower surface of the movable plate 15 is movably connected to the upper surface of the base plate 1.

[0034] When the operator starts the drive motor 13, the first threaded rod 14 will start to rotate, and the first moving plate 15 will start to move left and right under the drive of the first threaded rod 14.

[0035] In some examples, a first limiting rod 16 is fixedly connected to the lower side of the left surface of the mounting post 12. The right end of the first limiting rod 16 passes through the mounting post 12 and the first moving plate 15 in sequence and extends to the right side of the mounting post 12. The outer surface of the first limiting rod 16 and the inner surface of the first moving plate 15 are movably connected.

[0036] The design of the first limiting rod 16 plays a role in ensuring the stability of the first moving plate 15 during movement.

[0037] In some examples, a pneumatic cylinder 17 located above the socket plate 11 is fixedly mounted on the inner surface of the first moving plate 15, and a machining tool 18 is fixedly mounted on the front end of the pneumatic cylinder 17.

[0038] When the operator starts the pneumatic cylinder 17, the machining tool 18 will begin to move forward, thereby machining the workpiece.

[0039] In some examples, a mounting bracket 19 is fixedly connected to the outer surface of the machine tool 2. The lower surface of the mounting bracket 19 is fixedly connected to the right end of the upper surface of the processing table 3. The lower surface of the mounting bracket 19 is movably connected to the upper surface of the recycling bin 25. A power motor 20 is fixedly installed at the top of the right surface of the mounting bracket 19. A second threaded rod 21 is fixedly sleeved at the other end of the output shaft of the power motor 20. The left end of the second threaded rod 21 passes through the mounting bracket 19 and extends to the left surface of the mounting bracket 19.

[0040] When the power motor 20 starts running, the second threaded rod 21 will start to rotate.

[0041] In some examples, the outer surface of the second threaded rod 21 is threaded with a second movable plate 22 located inside the mounting bracket 19. The top of the second movable plate 22 is movably connected to the inner surface of the mounting bracket 19, and a tip 23 is fixedly installed on the lower side of the left surface of the second movable plate 22.

[0042] The rotation of the second threaded rod 21 will drive the second moving plate 22, thereby causing the second moving plate 22 to move left and right as a whole.

[0043] In some examples, the right surface of the mounting bracket 19 is fixedly connected to the second limiting rod 24 located in front of the second threaded rod 21. The left end of the second limiting rod 24 passes through the mounting bracket 19 and the second movable plate 22 in sequence and extends to the left surface of the mounting bracket 19. The outer surface of the mounting bracket 19 and the inner surface of the second movable plate 22 are movably connected.

[0044] The design of the second limiting rod 24 ensures that the second moving plate 22 remains stable during left and right movements.

[0045] In some examples, a first limiting plate 26 is movably connected to the left surface of the recycling bin 25, and a second limiting plate 33 is movably connected to the right surface of the recycling bin 25. The lower surfaces of both the first limiting plate 26 and the second limiting plate 33 are fixedly connected to the upper surface of the base plate 1.

[0046] The design of the first limiting plate 26 and the second limiting plate 33 serves to restrict the movement direction of the recycling bin 25.

[0047] In some examples, the inner surface of the first limiting plate 26 is movably fitted with an insert plate 27, the left end of the insert plate 27 is movably connected to a fixing plate 29, the lower surface of the fixing plate 29 is fixedly connected to the upper surface of the base plate 1, and the lower surface of the insert plate 27 is fixedly connected to a cylinder 28.

[0048] The rear surface of the insert plate 27 and the front surface of the recycling bin 25 are on the same plane. When the insert plate 27 contacts the front surface of the recycling bin 25, the position of the recycling bin 25 will be restricted by the second limiting plate 33, the first limiting plate 26, the insert plate 27, the mounting bracket 19 and the processing table 3.

[0049] In some examples, a second motor 30 is fixedly mounted on the front surface of the machine tool 2, and a second round shaft 31 is fixedly sleeved on the other end of the output shaft of the second motor 30. A drive rod 32 located below the insert plate 27 is fixedly sleeved on the outer surface of the second round shaft 31, and the inner surface of the drive rod 32 is movably connected to the outer surface of the cylinder 28.

[0050] When motor 30 starts running, shaft 31 and rod 32 will start to rotate. The rotation of rod 32 will drive cylinder 28, which will cause cylinder 28 and plate 27 to move to the right.

[0051] The working principle and usage process of this disclosure are as follows:

[0052] First, the operator starts the machine tool 2, drive motor 13, pneumatic cylinder 17 and power motor 20 to complete the clamping and processing of the crankshaft workpiece. Then, the processed crankshaft workpiece is taken out. Next, the operator starts motor 7. As motor 7 runs, the first round shaft 8 and the drive rod 9 will start to rotate. The rotation of the drive rod 9 will drive the driven rod 10, causing the driven rod 10 to start rotating. The other end of the driven rod 10 will drive the connecting plate 6, thereby causing the connecting plate 6 to move forward as a whole. Finally, as the connecting plate 6 moves as a whole, the remaining processing debris above the processing table 3 will be pushed into the recycling box 25 by the push plate 4.

[0053] When the recycling bin 25 contains a large amount of debris that needs to be recycled, the operator starts the second motor 30. As the second motor 30 runs, the second shaft 31 and the drive rod 32 will start to rotate. At this time, the inner surface of the drive rod 32 will drive the cylinder 28 and the insert plate 27, thereby causing the insert plate 27 to move to the left. Finally, when the insert plate 27 contacts the fixing plate 29, the insert plate 27 will no longer contact the recycling bin 25. At this time, the fixing of the recycling bin 25 is released, and the operator can pull out the recycling bin 25 to recycle the metal debris inside the recycling bin 25.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
